| Research Abstract |
In this study, the dose and mechanical accuracy in irradiation field for intensity modulated radiation therapy using the charge coupled device camera-organic phosphor with area type detector system was evaluated. The area type detector, which is made from plastic scintillator known as water equivalent material, and reflecting mirror were fabricated. Acquisitions of information such as stopping positions and moving distance related to multileaf collimator, and absorbed dose were able to obtain simultaneously with high precision easily. The system was achieved within the precision at clinical adaptive level, and the improvement of the quality assurance and more safely treatment were expected.
